Successfully revived my 4830TG recently.

Replaced 5200mAh oem battery, power adaptor & samseng 870 evo SSD. Still on Windows 7 (checking if Windows 10 can be installed without issues or not).

What a legendary laptop. Built like a tank. However some plastics parts become brittle and Del key is dead. 10-years old but still soldiers on.

where you bought the battery

Shopee. Couldnt find an original replacement though.
The battery in 4830tg is not easy to replace haha

You can try email to hsnquote@highpoint.com.my to purchase the laptop charger. My sis got hers few months ago replaced. Original
